Hi i'm burning my brains trying to cast shadows .I can't make them using extensions since i have an ATI Radeon9200 that doesn't seem to support ARB_depth_texture or ARB_shadow.What other way could i try? Thanks a lot!

Stencil buffer shadows?

Really not that hard to achieve, although you need to ensure that you create the rendering context to support them.

They aren't extensions though, AFAIK.

Use shadow volumes (using the stencil buffer) or maybe shadowmaps which you can do using render to texture and copying the depth buffer to a texture (GL_DEPTH_COMPONENT).

There are a few basic shadow volume tutorials on the net (see nehe.gamedev.net for example) as well as shadow mapping, they won't neccesserily need extension.
